SPLICE FOR UNDERGROUND CABLES,

EPECIFICATON forming part of Letters Patent No. 346,942, dated August 10, 1886.

Application lled February 2, 1886. Serial No. 190,655. (No model.)

To all whom it 'may concern.-

Be it known that I, WILLIiM It. PATTER- soN, a citizen of the United States, residing` at Chicago, in the county of Cook and State of Illinois, have inventeda certain new and useful Improvement in ,Splices for Telegraph-Cables, of which the following is a full, clear, concise, and exact description, reference being` had to the accompanying drawings, forming a part of this specihcation.

My invention relates to telegraphcables in which the conductors are separately insulated and made water-proof, of which kerite cables may be taken as a typee In splicing such cables it is very difficult to make good joints by any ofthe methods now in use. The method now in common use is to cover the splice of each conductor separately with the same compound used to protect the rest of the conductor, and then to vulcanize the covering thus formed over the splice. This method is difficult, expensive, and uncertain. In splicing such a cable with one in which the core is not waterproof, but is protected in mass by lead pipe,even greater difficulties arise by the use oi' any ol' the well-known methods. XVhen the splines of the individual wires are separately wound with tape or with vulcanized material, it is ditlicult to make any tesis or to piel; ont any individual wire.

The object oi" my invention is to provide means for splicing herite or other cables of this class, in which the conductors are separately protected,with one another, or with cables in which the cores are protected from moisture in a mass by lead. pipe or otherwise. Y

By the use ofniy invention the separate wires are made accessible, and the troubles and uncertainties heretofore experienced avoided.

In the drawings, which are illustrative of my invention, -Figure l is a sectional view showing my invention embodied in a splice between two different kinds of cable. Fig. 2 is a plan view of the Y-piece which is placed over the Fig. 3 is an enlarged side view oi' the perforated templet or plug through which the separate wires of the cable to be spliced are drawn, Fig. 4.- is an. end view thereoi.

Like parte are indicated by similar letters of reference throughout the different figures.

Iucable a the conductors are separately protected-for example, by okonite, kerite, india-rubber, or any other vulcanized coinponnd. Cable D consists of a core of separately insulated and parafiined wires, which is inclosed in a lead pi pe. ductors of cable a are drawn separately through the perforated plug c far enough to give sufficient length for splicing'. The plugis then inserted in the end of the piece of lead pipe d, which is secured to the brass section e by a wipe-joint, as shown. This brass section is screwed, as shown, into the castingf of the Y or T piece. The ends ofthe wires thus drawn in are then laid bare and spliced,respectively, to the corresponding wires of the cable I). I preferably put glass tubes over the joints thus formed, as shown in the drawings, and as described in my Patent No. 233,162, of Octobe In order to prevent moisture from in any way penetrating to the splice,Ill the space above the plug in and about the wires with, preferably,rosin and shellac, using about four parts of rosin to one of shellac. Other substances of a similar character may be used. I, moreover, screw the cap g into the casting, thus forming a closed space at the joints ofthe wires. By thus protecting the joints it is evident that no moisture can penetrate thereto. By removing the cap g it is evident that the separate wires may be readily reached for tal;- ing out a wire, making tests, or for any other purpose.

In Fig. 2 I have shown a small cable,si1nilar to cable a, branched to the Y-piece. The ends of the conductors of this cable may be spliced, as above described, within the cap, so as to connect in either direction with the wires of the other cables branched to the saine Y-piece. The ends o t this cable will be protected in the saine manner as cable ,hereinbefore described. I have thought it only necessary to show a portion of the filling It and the covered wires extending a short distance from the Y-piece.

I have shown and described the cable b as spliced to cable a. This cable is of the class described in my Patent No. 248,209,0f October ll, 1881, in whichl the core of separately-insulated wires is protected by alead pipe. The sleeve which is placed over the lead pipe of The ends of the con-- and more complete description of this sleeve reference is made to my Patent No. 277,335, of May 8, 1883.

It is evident that my invention is of special utility in splicing separately-connected wires with the conductors of cables protected in a mass; that it may be used to advantage whenserted, the filling in said pipe,and theY-piece placed over the joints of the conductors, whereby moisture is prevented from penetrating to the joints, substantially as and for the purpose specified.

2. rIhe combination, with the separatelyproteeted wires of cable a, of a perforated plug or templet, the pipe in which the said plug is inserted, the filling in said pipe, and the branched pipe placed over the joints of the conductors, whereby moisture is prevented from penetrating to the joints, substantially as and for the purpose specified.

In witness whereof I hereunto subscribe my name this 30th day of January, A. D. 1886.

WILLI AM It. PATTERSON.
